He also has fingerless gloves with green stashes near his gloves. The Omnitrix is now on his belt instead of his chest.

11-year-old Four Arms in Omniverse looks the same as the original series but now has green eyes and the Omnitrix symbol on his shoulder is now green.

Four Arms Strength

Four Arms' most prominent ability is his super strength, being able to lift several times his own weight, punch through various resilient materials and even create strong shockwaves by clapping his four hands together or slaming his fists on the ground. He can jump several times his own height. His strength allows him to use anything heavy as a weapon, from big rocks he can throw several feet away to beams and pillars that can be used as clubs. Another feature is his endurance and resilient skin, being almost fire and laser-proof.


Sometimes Four Arms' bulk is a disadvantage; all the extra muscle mass makes him relatively slow, and his size, likewise, makes using things designed for smaller species difficult.
